Dragon Diamond

The Diamond, that had clinked its way into the bottom of a jagged rock pool, had been deposited into the dune, by a Dragon of the Fires. He had in fact coughed it up quite literally, being partial to the forest coal, feeding on refuse and small animals as well. It was, of course, the nuggets of coal that had gone to make Tindle’s jewel.

What may be a stone in the gall to a man, is a diamond in the intestine, to these most ancient of beasts.
